Polygon scanning motor jig for processing rotary polygon mirror used for the polygon scanning motor and processing method of the rotary polygon mirror using the jig

摘要

The present invention relates to a jig and the processing method, if rotation with respect to the jig for processing the light rotary polygon mirror used for the scanning polygon motor and the polygon scanning motor.; The present invention, with the shaft; And when the press-in shaft holder rotor is provided in a; Is coupled to the upper outer peripheral surface of the holder, the outer face forms a face of a predetermined angle, and the surface has a reflective film is coated with mirror glass material; Is located at the rotor lower portion, with a rotor stator for generating a rotating electromagnetic forces; as being, including, rotation, if by the light forming the glass can be made to cost reduction, particularly if the rotation of a glass jig for shaping the light If the precision of turns through such an advantage could seek a job it can be processed by improvement of honor.
